@MookyTroubadour do you mean top-down or bottom-up?
Because bottom-up leadership is usually what you want... that's where the people in the field (usually technical staff) drive the decisions being made, instead of out-of-touch bureaucrats, execs, and administrative functionaries with inflated egos.
@IrelandTorin as a former Amazon guy, I appreciate concise and clear mandates, a la Jeff’s API mandate: https://nordicapis.com/the-bezos-api-mandate-amazons-manifesto-for-externalization/
